Boyfriend’s baby mama?

My boyfriend has 3 boys with the same woman and they’ve recently got a divorce.
I’ve asked him when do I get to meet her since her boys stay at mine and my bf’s house when they have the chance
He said to me he’s trying to protect me from her because she’s a bitch to everyone and will be a bitch to me.
Everyone in his family says she’s a bitch and they don’t like her, so I understand why he says that. But I do want to meet her cause I love her kids.

Is this understandable?
